Integration of a better email server

Hula Email Server will be "released" within the next 3-4 months as their first release. Besides the fact that Novell has ~12 full time developers working on it, it is based off of the Novell Netmail codebase. Netmail has been around for years and is a very solid product.

has anyone given scalix a try? I am interested if the webaccess is configurable to operate with another mail server like postfix (curretly browsing their site for this info) as I am just looking for another god webaccess for email.
